a jar contains 5 blue marbles, 8 red marbles,4 white marbles,and 3 purple marbles. suppose you pick a marble at random not looking. what is the chance of getting a red marble

Total = 5+8 +4 +3 =20

P( red) = 8/20 = 2/5 = 0.4

I got it right.

To calculate the chance of getting a red marble, we need to determine the total number of marbles in the jar and the number of red marbles in the jar.

Given:
Blue marbles = 5
Red marbles = 8
White marbles = 4
Purple marbles = 3

Total number of marbles = Blue + Red + White + Purple = 5 + 8 + 4 + 3 = 20

The chance of getting a red marble can be calculated as:
(Number of red marbles / Total number of marbles) * 100

Chance of getting a red marble = (8 / 20) * 100 = 40%

Therefore, there is a 40% chance of picking a red marble from the jar.

To find the chance of getting a red marble, we need to determine the total number of marbles and the number of red marbles in the jar.

The total number of marbles in the jar is the sum of blue, red, white, and purple marbles: 5 + 8 + 4 + 3 = 20.

The number of red marbles is 8.

To calculate the probability, divide the number of red marbles by the total number of marbles:

Probability of getting a red marble = Number of red marbles / Total number of marbles
= 8 / 20
= 0.4 or 40%

So, the chance of picking a red marble is 40%.
